1.3 Device description
Arrow
Standalone is a radio module with
EVO
pulse input compatible with Maddalena
water meters and with those of other
brands. The device allows for measuring,
transmitting and remotely reading the con-
sumption values and the alarms using a
wireless transmission technology.
4
The following alarms are managed: maxi-
mum flow exceeded (limit can be activated
and configured), backflow (limit set and con-
figurable), leak and mechanical fraud (cable
cutting).
Arrow
Standalone is compliant with the
EVO
wM-Bus data communication protocol de-
fined at European level by Standard EN
13757. This guarantees a high level of inter-
operability with various reading systems on
the market, including third-party systems.
Arrow
Standalone is also OMS certified
EVO
(www.oms-group.org).
The factory set-up can be modified via radio
signal at a later point using the special con-
figuration kit (USB transceiver and relative
software), supplied separately.
The main technical specifications of the Ar-
row
Standalone design are:
EVO
– input via four-pole cable of the follow-
ing signals: pulses (flow meter revolu-
tions), flow direction, anti-fraud, earth.
Thanks to these data, the module calcu-
lates the volume (both directions), man-
ages alarms and memorises the data in a
non-volatile memory;
– M-Bus (EN 13757) 868 MHz radio wire-
less communication interface that
allows remote reading in both mobile
(walk-by) and fixed (AMR) scenarios,
using the same factory set-up (trans-
mission interval);
– lithium battery that guarantees long-
term power supply (15 years + 1)
– support ring nut that allows the module
to be attached to the QuadraPlus sensor
easily. Alternatively, it can be fixed to the
wall using the two plugs supplied or to the
pipe using clamps.
